! Description:
!   Preprocessing rules for determining how large an unformatted 
!   data record is when using Fortran write.  This does not affect
!   netCDF output at all.

! Notes:
!   New directives will need to be added to port CLUBB GrADS output
!   to new compilers that do not use byte size record lengths.

!   Early Alpha processors lacked the ability to work with anything
!   smaller than a 32 bit word, so DEC Fortran and its successors
!   (Compaq Visual Fortran, newer Intel Fortran, etc.) all use 4 
!   byte records.  Note that specifying byterecl on Alpha still 
!   results in a performance hit, even on newer chips.
